Etymology

Unknown. Some authorities derive this word from Mexican Spanish jacal, from Nahuatl xacalli (“adobe hut”). Alternatively, the word may instead come from ramshackle/ramshackly (e.g., old ramshackly house) or perhaps it may be a back-formation from shackly. Compare Tavringer Romani hak (“place, house”), Traveller Norwegian hak (“place”).

Obsolete variant of shake. Compare Scots shag (“refuse of barley or oats”).

From shagged or shagged out.
